Answer:
Explanation:
Considering the atmosphere of the primitive earth to have contained water vapor, carbon dioxide, carbon monoxide, methane, and ammonia and/or nitrogen, then in the presence of an energy source, such as sunlight or lightning, a number of small molecules like hydrogen cyanide, HCN, are formed.
Answer:
This question is incomplete as it lacks options, however, it can be answered. The answer is:
CARBON DIOXIDE (CO2)
Explanation:
Cellular respiration is the process by which glucose is broken down in an organism's cell to release energy. Although the process involves series of reactions, however, the general equation is as follows;
C6H12O6 + 6O2 ➡ 6CO2 + 6H2O + energy
Based on the above equation, the inputs are glucose and oxygen while the outputs are carbon dioxide and water. Carbon dioxide (CO2) is the major byproduct of the respiration process.

Answer: A. Make A Guess
Explanation: A hypothesis is a statement you test, first you have to come up with an idea or theory to test, which would then become your hypothesis.
In natural selection, there are three main things you need to know. There must be a variance in the genepool of course, or else to selection or evolution will take place. There also must be a selective force and time. Now, lets say that there is a population of many colored moths. But lets say that the brown colored moth blends in with the environment. This means that predators (selective force in this case) will have a much harder time finding these brown moths instead of easily finding some of the other colored moths (variation). This means that the brown moths will survive at a much higher rate because the are harder to find, and over time, the gene pool will narrow down to just brown moths because the rest of the moths die out due to predators and competition. This also means that this moth species has evolved over time to just become the brown colored moths only. Hope you can understand this but feel free to ask for clarification.
